R help - Nov 2020 - calling r from java

This doesn't answer your question, but may be relevant.
I have a java-based application that works on a similar principle.
(The code is horrendously bad and most of it should be thrown away).

I'm planning to write a terminal emulator, in the near future.
(Currently, second place on my top-level todo list).

The primary objective is to build object-oriented and message passing
APIs on top of the core terminal emulation system, with at least some
cross platform functionality.
Noting that, in my opinion, the cross-platform aspect is more
important for R, than in many other IPC topics.

Hence, I'm interested in hearing "wishlist" items for such APIs.

Thanks all, I'll go for https://www.rforge.net/JRI/ and the libraries
in maven https://search.maven.org/search?q=jri

The maven library is build from  here 
https://www.rforge.net/rJava/files/ back in 2017.

After this no new libs are published to maven.

It would be nice (understatement) if publishing new rJava components to
maven becomes a regular part of R deveopment processes.

This would promote R use from Java which I think is good.

And of course I can help.

Bye, Eduard
